A full-frame 40 mm lens with an STM stepping motor. It takes up little space on the camera, focuses quickly and quietly, and you set the aperture with the ring right on the lens.

The 57° angle of view comes close to the natural view of the eye. That makes the lens a good fit for street, travel and documentary photography and environmental portraits.
STM stepping motor, minimum focus distance of 0.4 m.
Including ED and aspherical elements.
Clicked aperture ring, 7 aperture blades.
A lightweight lens in a metal body with a 52 mm filter thread.
The STM stepping motor focuses quickly, quietly and precisely, so the lens works for both stills and video. The autofocus supports the camera's face detection.

The F2 aperture lets in more light, allowing faster shutter speeds and handheld shooting in low light. Wide open, soft background blur separates the subject from the background.

The optical design of 9 elements in 6 groups includes low-dispersion ED elements and aspherical elements. They reduce chromatic aberration and keep sharpness and contrast high.

The lens body is made of 5052 aluminium alloy, and the lens weighs only 167–176 g. Paired with the camera, the setup stays light and compact even when carried all day.

You set the aperture with the ring from F2 to F16, and every step is clearly felt, so you can change it without looking at the scale. The aperture has 7 blades.

The USB-C port for firmware updates sits in the rear lens cap, so the lens body stays free of extra elements and you load the firmware straight from a computer.
